Though she's no stranger to the spotlight, the former Nickelodeon star has only been making her own music for a year—but what a year it's been! Since performing at the VMAs pre-show last year, Ariana has dropped hit after hit and taken the stage at basically every important event ever. We don't know what's skyrocketed the most in the last 12-ish months—her fame or her style.

Below are a few of our fave looks from Ariana's performances–peep them and then join us in guessing what she'll wear on August 24!

No one appreciates a full-skirted tea-length frock quite like Ariana. And if floral is involved? All the better. Earlier in her TV career, Ariana was never not seen in a flowery sundress and it's nice to see she hasn't veered too far from her signature style.

CROP TOPS + MATCHING MINIS

Both retro and futuristic at once, Ariana's midriff-baring tops paired with itty-bitty minis make a major statement on the stage—especially when worn with those near-omnipresent white go-go boots that would make Sally Draper jealous.

LEOTARDS + FLYAWAY SKIRTS

What's a young performer supposed to wear when a leotard just doesn't provide enough coverage but a skirt feels *too* covered-up? This, apparently.

POUFY PROM DRESSES

If you spot Ariana in a sparkly, sequined confection that looks like it could be a prom dress, well, that's because it probably is. She's performed in dresses designed by Sherri Hill (who designed the peach number), Jovani (the brand behind that little black dress), and a bunch of other labels lauded by prom queens everywhere.

What will she wear to hit the 2014 VMA stage in Englewood, California? We'll have to wait and see when it all goes down on Sunday, August 24 at 9 p.m. EST on MTV!
